Trachydium.] LXX. UMBELLIFER^. (C. B. Clarke.) 673 



SIKKIM; Tungu, alt. 13,000-14,000 ft., J. D. H. 



Stem 0, crown greatly thickened. Leaves with ascending fine hairs on the mid- 

 rib. Umbel solitary, sessile, with some of the rays again umbelled. JBracteolcs 3-6, 

 ^-1 in., 3-fid or pinnatifid. Carpophore stout, 2-fid. Fruit nearly as of 71 dissectum, 

 but the ridges less acute, the style-bases less prominent. 



5. T. obtusiusculuni, C. B. Clarke; cauline leaves pinnate pinnze 

 pinnatifid ultimate segments lanceolate subacute, fruit ovoid-oblong narrowed 

 upwards, ridges narrow undulated not rugose. Ligusticum obtusiusculum,

Stem (including the terminal peduncle) often 1 foot, grooved, hollow. Kadical 

 leaves (including the petiole) 3-4 by 1 in., in Sikkim examples twice as large as Nipal 

 ones; pinnae 7-11, segments oblong toothed or lobulate. Bracts of a dilated 

 narrow oblong entire petiole and sub-bipinnate limb with narrow remote segments 

 in Sikkim examples, ovate pinnatifid with approximate broad lanceolate segments 

 in Nipal ones. Fruit ^ in. ; style-bases conical, prominent ; primary ridges lax ; 

 pericarp thin, somewhat inflated ; vittae usually 2 between the primary ridges ; 

 carpophore 2-fid. Seed semiterete, dorsally subcompressed, hardly concave on the 

 inner face. 



VAR. stricta', ultimate segments and bracts more acuminate, primary rays shorter, 

 fruit more truncate less narrowed upwards. Trachydium, sp. 6. Herb. Ind. -Or,. 

 H.f. $ T. Sikkim, Chola Pass, alt. 10,000-12,000 ft., ./. D. H. This may be a 

 distinct species. Stems very erect, rays of the umbel 11 5 in., not much divaricate; 

 but the only distinction of importance is in the fruit which, though not well ripened, 

 is unlike that of T. obtusiusculum at the same stage. 



6. ELJEOSTICTA, Fend. 



Annual herbs, glabrous, erect, corymbose upwards or simple. Leaves 1-3- 

 pinnate, ultimate segments linear. Umbels compound ; bracts and bracteoles 

 several, scarious. Calyx-teeth 0. Petals obovate, emarginate. Disc depressed, 

 inconspicuous. Styles short. Fruit elliptic, truncate, laterally compressed, 

 didymous ; primary ridges very slender or 0, vittae in each furrow 3-1, minute ; 

 carpophore 2-partite or entire. Seed lunate, margins incurved, hence broadly 

 grooved on the inner face. DISTBIB. Species 4, in Western and Central Asia. 



This genus is placed by Bentham (Gen. PL i. 896) under Conopodium, but differs 

 in the short truncate fruit, the deeply grooved seed, and scarious bracts. 



1. E. meifolia, Fenzl in Flora 1843, 458 ; bracts 5-6 lanceolate, brac- 

 teoles similar but smaller, fruit broader than long. Scaligeria meifolia, Boits.

 Baiss. in Ann. Sc. Nat. ser. 3, ii. 62. 



PUNJAB PLAIN ; Aitcheson. DISTRIB. Persia, Syria. 



Hoot fusiform. Stem 1-3 ft., erect, panicled upwards or (in the small Indian ex- 

 ample) simple. Kays of the umbel 5-11, f-l in. Pedicels 6-12, in., Fruit 

 ^_ by _L in., depressed didymous ; ridges obsolete ; vittse minute, 2-1 in each furrow. 

 The Indian solitary example may be a new species, but is more probably only a 

 small specimen ; the fruit is even smaller than in E. meifolia type, the carpophore 

 subentire.
